The JSB safety relay from ABB has two inputs, which both have to be closed to keep the safety output contacts closed. This makes the device ideally suited to two hand safety control systems, however can be also used in many other safety control applications. When the JSB safety relay from ABB is used as a two-hand device relay, both buttons have to be pressed within 0.5 seconds of each other in order to close the outputs.
